Introduction to Xigou: Xigou is 12 kilometers deep and rises to an altitude of 2,000 meters above sea level (measured altitude table data). It can go around to the alpine shrub area below the main peak of Wula Mountain, Dayabei Peak (2,324 meters). From the bottom, there are continuous boulders. When reaching the middle and upper parts, the rocks become extremely clean and beautiful, with artistic shapes and strong ornamental value. At the water flow point of the ravine at an altitude of 1,200 meters (1.5 kilometers into the Xigou), the rocks spread out horizontally in the form of steps. The pink, gray and white rock surface in the ditch is like a huge stone wall or stone bed across the valley, tens of meters wide and tens of meters high. Its large area is incredibly smooth and complete. There are large concave holes on the rock surface, which are obviously caused by the erosion of springs and waterfalls over the years. Beautiful and clear mountain water flows down from such boulders, forming mountain streams, springs and waterfalls.
